Problems solved by technology

[0002] At present, there is a common problem among all manufacturers of round latex wire, that is, to simply dispose of dry rubber waste, or to sell it at a lower price. The effect of dry glue waste recycling in production research and development is still not good, polluting the environment and increasing production costs

Embodiment 1

[0050] Example 1: Recycling of Dry Rubber Waste and Preparation of Latex Silk

[0051] Pulverization: the dry rubber waste is pulverized by an ultrafine pulverizer to obtain a powder;

[0052] Stirring: Mix the obtained powder with petroleum ether in a weight ratio of 1:2 and place it in a 13-ton iron tank coated with an isolation layer and internally coated with an anti-rust layer, and stir;

[0053] Centrifugation: solid-liquid separation is achieved through a centrifuge;

[0054] Collect the liquid obtained by centrifugation, and add ammonia water with a volume ratio of 0.1% to keep fresh to obtain regenerated glue;

[0055] Regenerated glue: natural rubber latex is mixed in a volume ratio of 1:2 to obtain a mixture.

[0056] Process steps:

[0057]Mixing and stirring: stabilizer (potassium hydroxide, 0.6 parts by weight), accelerator (MZ: 2-mercaptobenzothiazole zinc salt, 1 parts by weight and BZ: dibutyldithioamino Zinc formate, 0.5 parts by weight), vulcanizing ag...

Embodiment 2

[0063] Embodiment 2: Dry rubber waste recycling and latex preparation

[0064] Pulverization: the dry rubber waste is pulverized by an ultrafine pulverizer to obtain a powder;

[0065] Stirring: Mix the obtained powder with petroleum ether in a weight ratio of 1:2 and place it in a 13-ton iron tank coated with an isolation layer and internally coated with an anti-rust layer, and stir;

[0066] Centrifugation: solid-liquid separation is achieved through a centrifuge;

[0067] Collect the liquid obtained by centrifugation, and add ammonia water with a volume ratio of 0.1% to keep fresh to obtain regenerated glue;

[0068] Regenerated glue: natural rubber latex is mixed in a volume ratio of 1:2 to obtain a mixture.

[0069] Process steps:

[0070] Mixing and stirring: stabilizer (potassium hydroxide, 0.9 parts by weight), accelerator (MZ: 2-mercaptobenzothiazole zinc salt, 1 parts by weight and BZ: dibutyldithioamino Zinc formate, 0.5 parts by weight), vulcanizing agent (sul...

Embodiment 3

[0076] Example 3: Effect Test

[0077] See HG / T 2487-2011 for the detection method and HG / T 2889-2011 for the standard.

[0078] The test results are shown in Table 1

[0079]

[0080] As can be seen from Table 1, each physical parameter of the latex silk that the latex silk that the present invention obtains is made with natural latex is almost the same, all within the standard range, fully illustrates that the latex that the present invention makes meets the standard, satisfies the requirement of technology need.

Abstract

The invention provides a recovery method for waste of dry glue. The recovery method comprises the steps of smashing the waste; mixing a product after smashing with petroleum ether, stirring; carrying out solid-liquid separation by a centrifugal separator; collecting liquid obtained by centrifugation centrally; and adding 0.1% by volume of aqueous ammonia in the collected liquid for retaining freshness to obtain regenerated glue. The recovery method also comprises the steps of mixing the regenerated glue and natural latex according to a volume ratio of 1 : 2; adding a stabilizer, an accelerator, a vulcanizer and the like to obtain a mixture; and preparing latex threads by a series of processes. Parameters and physical properties of the latex threads prepared by the recovery glue obtained by the method provided by the invention are almost unanimous with those of the latex threads prepared by the natural latex, within a standard range, indicating that the recovery glue by the method can meet preparation requirements of the latex threads. Besides, the method is convenient for operations. The waste of the dry glue can be recovered reasonably, so that productivity can be saved efficiently and recovered circularly. The prepared latex threads can be used for providing demands of life.

Description

technical field [0001] The invention relates to the field of waste recycling, in particular to a method for recycling dry glue waste. Background technique [0002] At present, there is a common problem among all manufacturers of round latex wire, that is, to simply dispose of dry rubber waste, or to sell it at a lower price. The effect of dry glue waste recycling in production research and development is still not good, polluting the environment and increasing production costs. [0003] Therefore, be badly in need of a kind of method of dry glue waste recycling. Contents of the invention [0004] The purpose of the present invention is to provide a method for recovering dry rubber waste with good recovery effect. [0005] In order to achieve the above object, the present invention provides a dry glue waste recycling method, which is characterized in that it comprises the following steps, [0006] Pulverization: the dry rubber waste is pulverized by an ultrafine pulveriz...
